Uncompromised Headed Architecture in a Compact Footprint | Available at Trimira Audio
The Bowers & Wilkins 803 D4 Floorstanding Speaker brings flagship 800 Series Diamond technology into a more compact floorstanding design. Incorporating the iconic Turbine™ Head enclosure, Solid Body Diamond dome tweeter, and advanced Aerofoil™ bass technology, the 803 D4 delivers exceptional clarity, scale, and precision for high-performance two-channel systems.
Finished in elegant Gloss Black with light grey leather detailing, the 803 D4 combines sophisticated aesthetics with studio-inspired acoustic engineering.
The dedicated aluminium Turbine Head isolates the Continuum™ FST™ midrange driver, while dual 7-inch Aerofoil™ bass units deliver deep, controlled low frequencies with impressive speed and accuracy.
